The LOW PRESSURE SWITCH being activated might cause which annunciator to light up?

Explanation:
The LOW PRESSURE SWITCH is designed to monitor the fuel system's pressure within an aircraft. When activated, it indicates that the fuel pressure has dropped below the acceptable threshold, which could compromise engine performance and overall safety. In response to this condition, the BOOST PUMP is automatically activated to ensure adequate fuel delivery to the engine. When the LOW PRESSURE SWITCH is triggered, the corresponding annunciator light for the BOOST PUMP will illuminate, alerting the crew that the pressure issue has occurred and that the boost pump is now engaged to maintain proper fuel flow. This safety measure is crucial to prevent engine flameout or failure due to low fuel pressure conditions. The other annunciators—OIL PX, TRIM OFF, and ANTI ICE—are associated with different systems and conditions within the aircraft's operation and would not be activated by a LOW PRESSURE SWITCH signal. Therefore, the lighting of the BOOST PUMP annunciator provides a direct and specific indication of the low fuel pressure situation.
